1 Water-Only Colorants Narrow the Gap to Solvent-Borne Performance Mark W. Ellsworth, Ph.D. Technical Director, Global Colorants

2 Agenda Colorant basics CCA Colorant portfolio Comparisons of Water-Only Colorants and Universal Colorants

3 Terminology Colorant: Concentrated liquid dispersion of pigment. Also contains various levels of surfactants, dispersion aides, biocides, anti-settling agents and resins Types of Colorants Water-only Solvent-based Universal Colorants are added to paints, stains and other coatings to produce a desired color

4 Water-only colorants General features and uses Compatible with waterbased acrylics High pigment levels Low to zero VOC capable POS architectural In-plant tinting CCA products NovoColor IP 85xx NovoColor HP 89xx CCA advantage Tight color tolerances Low to zero VOC High pigment levels

5 Solvent-based colorants General features and uses Broadly compatible Volumetrically controlled Minimal to no impact on coatings performance Gloss Chemical Resistance Hardness CCA products OptiColor XP 41xx ExacTint 7xx CCA advantage Tight color tolerances Wide array of product to fit a variety of industrial applications

6 Universal Colorants General features and uses Water-based colorants formulated with additional surfactants and co-solvents Compatible in waterbased paints and some solvent-borne paints POS architectural and In-Plant applications CCA products NovoColor II 88xx 19xx Universal Colorants CCA advantage Tight color tolerances Broad compatibility in acrylic paints, alkyd paints, and stains High hiding products

7 Performance Tinting process Quality and consistency of color match Viscosity drop Tip dry Kick-out Final coating Block Tack Hardness Scrubs Gloss

9 Industrial & Wood Colorants Point of Sale and In Plant Use Solvent based OptiColor XP 41XX Series Broad compatibility with 2K urethanes, epoxies, alkyds, CAB/Acrylics, conversion varnishes, and nitrocellulose Primary Markets: Industrial Maintenance General Industrial and Wood In Plant Use Water based NovoColor SF SuperFine Series Designed for tinting of water based coatings and stains Superior fastness and transparency New and improved products coming soon

10 OptiColor XP 41XX Series Solvent-borne Industrial Colorants Wide compatibility, particularly in NC lacquers Low VOC 19% on average Hydroxyl functionality allows the grinding resin to react into urethane coatings Tightest tint strength and color specification in the industry +/- 1% Tint strength and de <1.0 FMCII, by volume Hegman grind 7.0 minimum

11 Industrial & Wood Colorants: OptiColor XP Highly recommended Recommended Limited use Rating for OptiColor XP

12 Architectural Product Lines Point of Sale Use Universal Colorants NovoColor II 88XX Series Low VOC according to 40 CFR Compatible with latex and solvent systems Water-Only Colorants NovoColor HP 89XX Series Low VOC as determined by ASTM D6886 Compatible with latex systems only In Plant Use Water based NovoColor IP 85XX Series High strength in plant dispersions for water based architectural and industrial systems Low VOC according to 40 CFR Primary markets are Wood Coatings, and General Industrial 2-Coat Applications, 1K and 2K systems

23 Conclusions and Next Steps We have identified VOC level, viscosity drop, water sensitivity, block and tack as some key test parameters to show value of using water-only colorants. We see improvement in multiple properties with water only colorants versus universal colorants. Remaining colorants in testing, with White Paper detailing the results to follow
